C is the main frame or body of the machine which may be connected With'and supported on a base (not shown), and is provided at its forward end with avertically disposed tribular head D.

Fixed to and rising from the fraine C at a p'oint in rear of head 'D is an-upright E, and

best-shown in Figs. 1, 2 and 6. nail-h vertic 'lly-disposed openinga, the side Walls of which are preferably rabbeted, Fig, 6, and the bottom of the hopper is pitched 0r in- ,clined-downward in three directions 1, 2 and The invention will be fully understood said opening a so as to assure nails placed in the hopper ravitating. to the opening.

pieferab v rabbeted. as illustrated, and. is designed to be moved rectilinearly up and down by means. presently described in detail The said nail-feeder G is arranged in the same vertical plane as the wall of the hop er F in which it moves, and its up er em Z, which is of a width to supp'ortan raise one on thesaid upright is fixed a nail-ho per-F,

-T e said per is provided at one side with a Movable vertica 1y through the said opening l'eof hop erF is a nail-feeder G which is also nail, isbeveled as best shown in Fig. 2.- At 4 the outer side of'that wall of the hopper F in which the nail-feeder G isarranged', is fixeda thin plate 0 of about the size andshape shown in Fig. 1, andvat the outer-side of said plate 0 is arranged an inclined nail guide H, the walls of which are arranged sufficiently far apart to receive the shanks 'or bodiesof the nails'between them butnot far enough to receive the heads of the nails.

vFrom this it follows that when the 'nail-;

feederG' is moved upward it will carry on its per F, and when said end 5 reaches the upper "edge of the plate a the nail will drop laterally will move (I own the fguidel to. the po sition s hownfli t 'dotted lines in Fig. -()ifthe ,incl-ined end I) one of the nails fromthe hop the guide and its head resting on theinclined upper, edges of said walls. It will also be apparent-that because of the inclination of t ejupp'er edges of the'guideiwalls, the nails from the said end i) of the feeder and over Ithe uppcr edge of plate 0 and'will assume an,

1 sa eeliiinth st fr t rea F a whi is to assure the nails assuming the position stated in the guide.

By reference to Fig. 1, it will be seen that the forward ends of the walls of the nailguide H are recessed at it so that the upper portions of said ends extend forward beyond the lower portions thereof. This will be better understood by comparing Figs. 1 and 5. Connected to and depending from the nail-feeder G is a bar- 6 through the medium of which the feeder is raised and lowered and on the said bar e is an arm f which carries the nail cut-off I on which is a forward projection g. The cut-off I is .of U-sha e, as shown in Fig. 7; and it isdesigned w on moved upward synchronously with the feeder G, to assume a position in the recess h of guide H and between the foremost nailand the following nail so as to preventmore than one nail passing to the nail-conduit J at a time.

The upper portion of the said nail-conduit J is slotted and arranged immediately in front of the forward end of the space between the Walls of uideH so as to enable the nails to pass whi e in an upright position from the guide to the conduit, and while still in an upright position to gravitate in the conduit. T e foremost nail, however, is normally prevented from passing from guide H to conduit J by the arm of a spring K which is connected at'i to the hopper F. Said arm of the spring K normally rests across the upper edges of the guide-walls in advance of the foremost nail, and itwill be apparent that when the bar e is moved upward, the projection g on cut-off I will engage the arm of the spring K and by raising the same will release the foremost nail and permit the same to pass to the conduit J. But one nail,however, can pass from the guide H to the conduit J since when the cut-off I moves upward to raise the spring K and release the foremost nail, said cut-off will assume a position between the foremost nail and the following nail. On the subsequent downward movement of the cut-off, I, the arm of spring K will reassume its position 'on the guide 11 so that the mentioned following nail will when released by the cut-off, assume a position against and be held' by the said arm of spring K.

The nail-conduit J extends downward and forward from the discharge end of the guide and the said gate is designed to be moved inward in the slot so as to catch and support a nail, through the medium of a coiled spring At the proper time in the operation of our machine, viz: when the bar e carrying the nail-feeder G, etc., is moved upward, the spring m is enabledto close the gate L so that said gate will catch and support the nail received in the conduit J from the nail-guide H. Then on the subse uent down movement of the said bar e'an its appurtenances,

a device in the form of an arm M, Figs. 1, 4 and 5, will press the pin p against the action of the spring m so .as to open thegate and enable the previously caug t nail to pass to the lower end of the nail-conduit Ji. e., to the position shown in Fig. 8.

N is a horizontal rock-shaft journaled in suitable bearings at the opposite side of the frame C, with reference to the bar e. said rock-shaft has fixed upon it the arm'M, and it also has fixed upon it an arm P, which arm P is connected to and arranged to transmit motion to the bar 6. The rock-shaft N is designed to be turned in the direction indicated by arrow by means hereinafter described, and it is returned to and normally held in the position shown by a pulling spring Q, Figs. 3, 5 and 6, which spring Q extends between and is connected to the frame C and an arm- R fixed on the rock-shaft N. When the rock-shaft N is returned to the position illustrated, the vertically movable bar e and its appurtenances will assume the positions illustrated, and the gate L will assume the position shown in Figs. 1, 4 and 6. In addition to the arms M, P and R, the shaft N is equipped with an arm S, Figs. 1, 3, 5 and 7, through the medium of which it is rocked in the direction indicated by arrow, as will be presently described.

'l, is an upright fixed to and rising from the frame C, at a point in rear of the head I), and U is a jaw-opener fixed, preferably in an adjustable manner on theupright 'l, and having a vertical opening t positioned above the head I); the side walls of the. said opening t being beveled or inclined upward and inward, as shown in Figs. 1. and 7, for a purpose presently set forth.

The head 1) communicates at 4, Fig. 8, with the lower end of the nail-conduit J, and in the said head is arranged and adapted to move up and down a tube V in which is a vertical slot 5, arranged when the tube V is moved upward to register with the opening 4 in the head and' thereby permit a nail to pass from the lower end of the conduit J into the tube V. In its lower end the tube V is The 30 i split tube W ereimovcd upward by the raisprovided with ri centre-l aperture 6 adapted I to hold it unit precedent to the driving there rend o'lthe said eperture 6 being tiered-or Muriel-shaped, its indicated by 7, to assure propfcr passage of the nails to the aperture.

N is rocked in the direction indicated by arrow through the connections described, to raise the nail-feeder G, the nail cut-ofi' I, and the nail retainer or spring K so as to effect the transfer of one imil froni the guidel'l to the 1 conduit J, and to assure the gate L being closed to catch the said nail. As the tube V moves upward and the slot 5 therein registers with the lower end of the conduitl the-nailtubesV and W', the jaw-opener or catch releaser U will engage the catch Y and automatically open the jaws of the same so as to release from said jaws the hammer head Z, when the external springs or the internal spring before described as complementary to the hammer will forcibly impel the hammer downward and cause said hammer to properly drive the previously positioned nail into the shoe. On the subsequent downward movement of the work-support A and the shoe B, the external springs or the internal spring complementary to the tubes V and W cause downward movement of the tubes to the position illustrated, at the same time causing the gate L to release the tack, when the o )cration described is repeated until the nai ing of the shoe or other work is completed.

It will be gathered from the foregoing that our novel machine is designed more especially for use by shoe-makers or cobblers, and it will also be gathered that any means suitable to the purpose of the invention may be employed to raise the tubes V and \V. For this latter reason we do not desire to be understood as confining ourselves to the employment of a work-support for effecting the purpose stated, though we prefer to employ a work-support such as shown or any other suit-able work-su )port. We would also have. it understood that without involving departure from the scope of our invention as defined in the appended claims, a nailfceding means other than that described may be employed in connection with the head I) and its appurtenances. In this connection, however, we desire it distinctly understood that the nail-fceding means shown and described is preferable because it is automatic and reliable in operation, and at the same time well adapted towithstand the usage to which such mechanism is ordinarily subjcctcd. stood that the nail-feeding mechanism described may be used in connect-ion with any nail-holding and driving mechanism othc,r than that described without involving dcparturc from the scope of our claimed invention, though for obvious reasons we prefer to cmploy the latter nail-holding and dniving mechanism.
